Product details
Overview
P4KE11AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on DC power rails and signal lines. It features a 10.5 V minimum breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 15.6 V maximum clamping voltage (VC) at 25.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE11AHE3/54 datasheet, P4KE11AHE3/54 pinout, P4KE11AHE3/54 application, or P4KE11AHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, thermal resistance data, and real-world use cases aligned with Vishay's official specification document 88365.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated junction and matte tin-plated leads solderable per J-STD-002. Its 10/1000 μs surge response delivers 25.6 A peak pulse current while limiting transient voltage to ≤15.6 V - critical for protecting downstream MOSFET gates and microcontroller I/O pins against inductive switching spikes.
The device exhibits 0.075 %/°C temperature coefficient of breakdown voltage and 66 °C/W typical junction-to-lead thermal resistance. It is rated for -55 °C to +175 °C operating junction temperature and qualified to AEC-Q101, confirming suitability for automotive under-hood applications where thermal stability and reliability are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 10.5 V - ensures reliable conduction onset above normal 9.4 V rail voltage, preventing false triggering during nominal operation |
| VWM | 9.40 V - maximum continuous reverse working voltage compatible with 9 V–12 V DC systems |
| VC @ IPPM | 15.6 V - clamped voltage at 25.6 A surge, defining safe overvoltage ceiling for protected ICs |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 μs waveform, sufficient for ISO 7637-2 Pulse 1/2a/5a compliance |
| IPPM | 25.6 A - peak surge current capacity enabling robust protection against ESD and load dump events |
| TJ max | +175 °C - high junction temperature rating supports placement near heat sources in engine control units |
| RθJL | 66 °C/W - low junction-to-lead thermal resistance enables effective heat dissipation through PCB copper pour |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | DO-214AA package; 10 V VWM; 17.0 V VC @ 24.9 A; same 400 W PPPM | Surface-mount footprint; lower thermal resistance (RθJA = 40 °C/W) but requires reflow-compatible layout | Select SMBJ10A when board space is constrained and automated assembly is required; verify PCB pad thermal relief for 175 °C operation. |
| 1.5KE11A | DO-201AD package; identical VWM/VBR/VC specs; 1.5 kW PPPM rating (higher surge capacity) | Through-hole alternative with larger case size and higher surge margin; not AEC-Q101 qualified | Choose 1.5KE11A for non-automotive industrial applications requiring higher single-event surge headroom, accepting larger footprint and no automotive qualification. |
Compared with P4KE11AHE3/54, SMBJ10A offers SMT compatibility and better thermal performance but lacks AEC-Q101 validation, while 1.5KE11A provides greater surge robustness in a larger through-hole package without automotive certification - making P4KE11AHE3/54 the optimal choice for cost-sensitive, AEC-Q101–mandated automotive and industrial designs requiring DO-41 fit.

FAQ
What is the maximum clamping voltage of the P4KE11AHE3/54 under surge conditions?
The P4KE11AHE3/54 has a maximum clamping voltage (VC) of 15.6 V at its rated peak pulse current of 25.6 A using the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during transient events. The P4KE11AHE3/54 maintains this clamping performance across its full operating temperature range.
Is the P4KE11AHE3/54 suitable for automotive applications?
Yes, the P4KE11AHE3/54 is AEC-Q101 qualified (as indicated by the HE3 suffix), meaning it has passed stress tests for temperature cycling, humidity bias, mechanical shock, and other automotive-grade reliability requirements. Its -55 °C to +175 °C operating junction temperature range and glass-passivated junction make the P4KE11AHE3/54 appropriate for under-hood and powertrain control module applications.
What does the "HE3" suffix indicate in P4KE11AHE3/54?
The "HE3" suffix in P4KE11AHE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions and confirms compliance with automotive reliability standards. The P4KE11AHE3/54 is specifically intended for mission-critical applications where long-term stability under thermal and mechanical stress is required.
How does the P4KE11AHE3/54 compare to bidirectional TVS diodes like P4KE11CA?
The P4KE11AHE3/54 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P4KE11CA is bidirectional with no polarity marking and symmetric clamping in both directions. The P4KE11AHE3/54 offers tighter VBR tolerance (10.5–11.6 V) and lower leakage at VWM, making it preferred for DC rail protection where reverse conduction must be blocked - unlike the P4KE11AHE3/54, P4KE11CA cannot be used in circuits requiring forward blocking.
What is the thermal resistance specification for the P4KE11AHE3/54?
The P4KE11AHE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient resistance (RθJA) of 100 °C/W with 10 mm lead length. These values are critical for calculating temperature rise during sustained power dissipation and confirm that the P4KE11AHE3/54 can operate reliably at up to 175 °C junction temperature when mounted with adequate copper thermal relief on the PCB.
